Q

Describe the bone response to implant placement?

A

First you have bleeding, then the tissue DIES (necrosis) then you get some resorption, and than alas—new bone formation!

**Tissue necrosis-no intuitive

Q

what’s so awesome about the titanium oxide layer?

A

stays biologically active for YEARS allowing for adaption. this can interact with water, mineral ions, and blood derived plasma proteins.

Q

Describe the initial contact with the implant?

A

First of all, you get a coating of the surface (oxide layer?) with PLASMA proteins, then clot formation.

INFLAMMATION because that’s the normal response of the bone, Necrosis, vascular ingrowth, collagen rich matrix, and then osteoblast synthesis of bone matrix.

Q

T/F

Primary integration is a biologic process?

A

false! PRIMARY is all mechanical- think of just the contact between the osteotomy and the implant- achieved through macro retentive features

Q

Osteoconduction

A

enhance the IN migration of bone from the surface of the osteotomy

MEANS that bone grows on a surface!
Conduct the bone to grow on the surface

Q

Osteoinduction

A

biologically manipulate the types of cells that grow onto the implant surface

Recruits immature cells? MAJORITY OF BONE HEALING

Q

Describe some of the micro retentive features of an implant?

A

machined surfaces, coated surfaces, sand or grit blasting followed by acid etching….
Increases the process of SECONDARY which is the biologic process

22
Q

Describe transmucosal attachment?

A

barrier epithelium is about 2 mm long and attaches to the implant abutment with HEMIDESMOSOMES….
the fibers run parallel.
CT fiers integrate to implant surface?

**generally you will have GREATER probing depths around implant.

23
Q

How much volume loss approximately occurs in the first 3 months?

A

2/3 of the entire volume loss…

within 12 months, you get about 50% reduction loss

24
Q

When the buccal plate is less than (__) mm, you should consider ridge preservation?

A

less than 1.5-2.0 mm

25
Q

How far away from the mental nerve should you place an implant?

A

at least 5 mm anterior to the mental foramen to avoid the loop of the mental nerve

26
Q

how many mm between adjacent teeth and implant?

A

1.5

27
Q

how many mm between adjacent implants?

A

3 mm

28
Q

How many mm from vital anatomical structures

A

AT LEAST 2 mm away.

29
Q

Where should you place the implant vertically?

A

at least 3 mm from the proposed gingival margin…to allow for the emergence profile.

30
Q

A graft transferred from a donor site to a recipient site within same individual?

A

autograft/autogenous

31
Q

graft from donor species that is the SAME as the recipient- from cadaver

A

Allograft

32
Q

graft from a donor species different than the other?

A

xenograft- from a pig for isntance

33
Q

inorganic material used as a bone substitute?

A

alloPLASTic…

FAKE and not as good

34
Q

Osteogenic

A

quality of an AUTOGENOUS graft (from same person) which enables it to lead to bone formation via the transplant of viable osteoblasts within graft. our goal for osteogenesis to occur

35
Q

how many mm of bone do we want past the implant?

A

2 mm of bone

36
Q

how long of implant do we want ideally for posterior teeth?

A

10-12 mm of implant

37
Q

When do we like to graft?

A

at the time of extraction- more predictable.

38
Q

Describe Siebert classification?

A

Class 1 =BL
Class 2= Apico coronal
Class 3= combo

39
Q

T/F

Implants have the same long term success when placed in grafted vs. native bone?

A

true

40
Q

Vertical augmentation- when there is 5 mm of native bone and implant can be placed at the same time?

A

Sinus tap=== vertical augmentation

41
Q

Describe a lateral window-

A

mixture of cow and cadaver bone. cow bones more radiopaque and stays around longer.

Sinus perforations- if <1 cm it’s probably okay, >1 cm try again

42
Q

How long should you wait before placing implants if you did a socket graft?

A

3-6 months

43
Q

how long to wait for implants if guided bone regeneration?

A

4-6 months

44
Q

how long to wait for implants if you did a sinus augmentation?

A

5-6 months

45
Q

how long should you wait before you restore the implant?

A

2-6 months

46
Q

how far below the crest of the bone should you place implant?

A

1 mm below

47
Q

What position determines the papilla morphology?

A

MD position

48
Q

What position determines the emergence profile?

A

AC

49
Q

what’s the magic number for MD space for a single implant?

A

7 mm???

50
Q

what should the thickness of buccal and lingual bone be for implant position?

A

1 mm

51
Q

how do you measure the crown height space?

A

measured from occlusal plane to the crest of the bone

52
Q

In order to ensure proper emergency, you need __ m between the implant and the CEJ of the tooth?

A

2 mm
